Mental health teams can recognise the limitations of what can be achieved and will respond to challenges to improve care in this context. Mental health is not a technologically driven service, although CNS drugs are now the highest net ingredient cost to the NHS of all drug groups. Still, drug costs are a fraction of the main expenditure on staff. There is evidence that mental health services create a vulnerability to relapse but they understand the need to encourage independence. Creating a more patient-centred service can actually reduce costs.
